Even more significant was the scene which occurred in 1074 in the council of Paris, where the holy St. Gauthier, Abbot of Ponthoise, undertook to sustain the decretal by which Gregory VII. prohibited attendance on the masses of married and concubinary priests. The assembly manifested its disapprobation of the measure in a manner so energetic that its unlucky advocate, after being furiously berated and soundly pummelled, was glad to escape with his life from the hands of his indignant brethren.[615] When such was the spirit of the ecclesiastical body, there was little to be expected from any internal attempt at reform. At the stormy synod of Poitiers, in 1078, the papal legate, Hugh, Bishop of Die, succeeded in obtaining the adoption of a canon which threatened with excommunication all who should knowingly listen to the mass of a concubinary or simoniacal priest,[616] but this seems to have met with little response. Coercion from without was evidently requisite, and in this case, as we have seen, Gregory did not shrink from subjecting the church to the temporal power. In Normandy, for instance, a synod held at Lisieux in 1055 had commanded the degradation of priests who resided with wives or concubines. This was, of course, ineffective, and in 1072 John, Archbishop of Rouen, held a council in his cathedral city, where he renewed that canon in terms which show how completely all orders and dignitaries were habitually liable to its penalties.[617] The Norman clergy were not disposed to submit quietly to this abridgement of their accustomed privileges, and they expressed their dissent by raising a terrible clamor and driving their archbishop from the council with a shower of stones, from which he barely escaped alive.[618] At length, in view of the utter failure of all ecclesiastical legislation, the laity were called in. William the Conqueror, therefore, in 1080, assisted the Archbishop of Rouen in holding a synod at Lillebonne, where the stern presence of the suzerain prevented any unseemly resistance to the adoption of most unpalatable regulations. All who were in holy orders were forbidden, under any pretext, to keep women in their houses, and if, when accused of disobedience, they were unable to prove themselves innocent, their benefices were irretrievably forfeited. If the accusation was made by the ecclesiastical officials, the offender was to be tried by the episcopal court, but if his parishioners or feudal superior were the complainants, he was to be brought before a mixed tribunal, composed of the squires of his parish and the officials of the bishop. This startling invasion of the dearest privileges of the church was declared by William to proceed from no desire to interfere with the jurisdiction of his bishops, but to be a temporary expedient, rendered necessary by their negligence. Nor was this remarkable measure the only thing that renders the synod of Lillebonne worthy of note, for it affords us the earliest authoritative
